Abstract
The structure of a sexithiophene derivative end-substituted by two bul ky triisopropylsilyl groups has been determined in an attempt to bette r understand the relationship between structure and the electronic and optical properties of polythiophenes. The synthesis and structural ch aracterization of derivative are described in detail and the unusual c rystal system that involves staggered parallel arrays of molecules and a strong deviation from coplanarity of the pi-conjugated backbone is discussed.
